Description
Technical field
The present invention relates to lubricating grease field, be specifically related to a kind ofly be exclusively used in lubricating grease of high temperature kiln car and preparation method thereof.
Background technology
High temperature kiln car production environment feature is continuously, high temperature, high humidity, heavy duty and many dusts, greatly, kiln environment temperature is high for weight-carrying capacity, and kiln car will to coexist long-play at the temperature of 200-250 DEG C with fire-resistant blank.Under the condition of high temperature, heavy loading, conventional molybdenumdisulphide lithium saponify, extreme pressure compound lithium, organobentonite lubricating grease etc. there will be charing, coking in long-time hot environment, and the molybdenum disulfide lubricant added mostly is burnt and is become fragile, and almost loses lubrication.And cause bearing to lose effectiveness, produce the phenomenon of wheel lock up.Often go out a car and all upgrade lubricant again to all clearing up bearing, be bound at substantial time and manpower, and maintaining makes enterprise's production cost increase considerably frequently, and efficiency reduces, and labour intensity strengthens.Therefore, high temperature kiln car lubricating grease must have very high thermotolerance, the performances such as good high temperature lubricating, resistance of oxidation, water resisting property and protective.
Along with the development of industrial technology, the energy-saving and cost-reducing problem becoming concern, has higher requirement to the lubricating grease that high temperature kiln car uses, good high-temperature behavior should be had, vaporization losses reduces, and good lubrication and sealing function are played in not thinning loss under high temperature and not oxidizable; Require that there is higher supporting capacity and friction resistant performance simultaneously; There is good pump-conveying property and low coking tendency, not blocking pipeline, meet and concentrate for grease lubrication system; There is longer work-ing life etc.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind ofly has good resistance to elevated temperatures, colloid stability, oxidation stability, water resisting property and pumping, low coking tendency and ash content, high temperature noncoking in use procedure, without the need to cleaning, as long as directly add, and preparation method is simple, easy to operate, what product result of use was good is exclusively used in lubricating grease of high temperature kiln car and preparation method thereof.
For solving the problems of the technologies described above, the invention provides a kind of lubricating grease method being exclusively used in high temperature kiln car, the ratio of weight and number of described grease composition raw material and each component is: base oil A 40-60 part, base oil B 30-50 part, stearylamine 4-8 part, quadrol 3-5 part, MDI(ditane-4,4 '-vulcabond) 3-6 part, oxidation inhibitor A 1-2 part, oxidation inhibitor B 2-3 part, rust-preventive agent 2-3 part, extreme pressure anti-wear additives A 1-2 part, extreme pressure anti-wear additives B 1.5-3 part, tackifier 5-10 part.
Preferably, described base oil A is the mineral oil 150BS of high viscosity deep refining, described base oil B is PAO synthetic oil, described oxidation inhibitor A is pentanoic, described oxidation inhibitor B is phosphoric acid fourth octyl group zinc salt, and described rust-preventive agent is alkenyl succinic acid, and described extreme pressure anti-wear additives A is tritolyl phosphate, described extreme pressure anti-wear additives B is potassium borate, and described tackifier are low-molecular-weight polyisobutylene.
Be exclusively used in a preparation of greases method for high temperature kiln car, described preparation method, specifically comprises the following steps:
(1) by formula rate, the base oil A of 30% and whole base oil B is dropped in saponification still, and be warmed up to 40-60 DEG C;
(2) stearylamine of formula rate, quadrol are put into saponification still and stirred, churning time is 5-10 minute, obtains mixture one;
(3) by formula rate, remaining base oil A is put in oil groove, and be warmed up to 60-80 DEG C;
(4) by MDI(ditane-4, the 4 '-vulcabond of formula rate) put in oil groove, fully stir until entirely molten, obtain mixture two;
(5) mixture two of step (4) is driven in saponification still, and mix with the mixture one that step (2) stirs, slow intensification, start temperature and stir 20-40 minute at 70-90 DEG C, then at the uniform velocity intensification 2-3 hour, stop when temperature being increased to 200-220 DEG C, obtain mixture three;
(6) mixture three that step (5) stirs is transferred in mediation still, when temperature drops to 140-160 DEG C, adds oxidation inhibitor A and tackifier, stir;
(7) when temperature drops to 120-140 DEG C, oxidation inhibitor B and extreme pressure anti-wear additives B is joined and is in harmonious proportion in still, and circulation shear 20-40 minute;
(8) when temperature drops to 90-110 DEG C, rust-preventive agent and extreme pressure anti-wear additives A are joined and be in harmonious proportion in still, and after stirring 10-30 minute, homogeneous under 15-30MPa pressure, degassed, sampling detects qualified rear discharging, obtains lubricating grease.
The beneficial effect of employing technique scheme is: adopt the lubricating grease being exclusively used in high temperature kiln car prepared by the formula of the technology of the present invention method and preparation method, also the lubrication of chain under other high temperature, low speed, the severe duties such as sinter machine, incinerator, regeneratory furnace, spray paint drying production line and bearing is applicable to, Applicable temperature is between-30 DEG C ~ 250 DEG C, lubricating grease disclosed by the invention has good resistance to elevated temperatures, colloid stability, oxidation stability, water resisting property and pumping, compared with lubricating grease of the prior art, there is following characteristics:
1, excellent resistance to elevated temperatures and oxidation stability: dropping point index is one of index directly perceived of its high-temperature behavior of reflection, and grease dropping point disclosed by the invention can reach more than 300 DEG C, can use under 250 DEG C of Working environments the long period; High-temperature oxidation stability is one of main use properties of lubricating grease, uses and have larger impact to lubricating grease.The oxidation stability of lubricating grease is with to prepare grease thickener relevant with basic oil properties, grease thickener disclosed by the invention is because of not metal ion, the metal catalytic effect of base oil oxidation under high temperature can be avoided, so have good high-temperature oxidation resistant stability.
